Time- and Temperature-Dependent Response of Acquired FV Inhibitors: Implications for Laboratory Diagnosis and Clinical Management. [PDF]

open access: yesJ Clin Lab Anal
This in vitro workflow illustrates the time‐and temperature‐dependent behavior of acquired FV inhibitors. Patient plasma was centrifuged and serially diluted, followed by parallel incubation at room temperature and 37°C. Serial measurements of APTT mixing test and residual FV activity were recorded across incubation time points to monitor inhibitor ...

On-orbit calibration and performance of S-NPP VIIRS DNB [PDF]

open access: yesSPIE Proceedings, 2016
The S-NPP VIIRS instrument has successfully operated since its launch in October 2011. The VIIRS Day-Night Band (DNB) is a panchromatic channel covering wavelengths from 0.5 to 0.9 m that is capable of observing Earth scenes during both day and nighttime orbits at a spatial resolution of 750 m. To cover the large dynamic range, the DNB operates at low,
